Common side effects of Lipitor (atorvastatin) include muscle aches, digestive issues, increased blood sugar levels, and liver problems. It can also rarely cause serious side effects like muscle breakdown and liver damage. On the other hand, ACE inhibitors, commonly used to treat high blood pressure, can lead to a dry cough, dizziness, fatigue, and kidney problems. Both medications may have additional side effects, so it is crucial to consult with a healthcare provider for personalized advice and monitoring while taking these drugs.
